Windows Service Pack Road Map shows WinXP SP3 not scheduled until next year. There may be a beta version out, according to some rumors, but it would NOT have been pushed to you.

Any Office updates you'd get would depend on the Office version you have. I don't find a single site that gives all updates for all versions, and my Office is old enough that I have to search it's details separately. We have Office 2003 and Office Pro (basically Office 2002) and haven't seen anything new that resembles what you got.
